Charter for Working Group

The TRILL WG has specified a solution for transparent unicastshortest-path and multi-destination frame routing in multi-hopnetworks with arbitrary topology. End stations, including Layer 3routers, connected to TRILL switches are assumed to be IEEE 802.1Qcompliant end stations. TRILL switches may be interconnected withmulti-access or point-to-point links of arbitrary technology.

The current work of the working group is around operational supportand additional extensions and optimizations of TRILL for theproperties of the networks on which it is deployed. The TRILL WG mayalso produce corrections, clarifications, and updates of existingTRILL RFCs.

The WG will work on the following items:

(1) Following on from the TRILL OAM requirements (RFC 6905), specify aframework and specific protocols for the handling of Operations,Administration, and Maintenance (OAM) in networks using TRILL,focusing on fault management and performance and preferring existingOAM mechanisms that might apply to TRILL, such as SNMP, Netconf/Yangand mechanisms based on the IEEE 802.1 CFM framework.

(2) Specify protocols to support "active-active" service to endstations that are multiply connected to a TRILL campus to provide themwith flow level traffic spreading and rapid adaptation to link failuresimilar to that provided by TRILL for TRILL switches.

(4) Specify protocols for TRILL over pseudowires and TRILL over IPtunnels, for example to connect branch office TRILL switches to acentral TRILL campus over the Internet.

(5) Specify extensions to the TRILL protocol to support multi-levelrouting to improve scaling and multi-topology routing to providedifferent topologies for different classes or types of traffic, basedexisting IS-IS multi-level and multi-topology routing facilities.

(7) Analyze the use of IS-IS security (RFC 5310) in TRILL anddetermine if any work is needed to accommodate any specific TRILLcontrol or data plane security leveraging IS-IS security.

(8) Produce an interoperability / implementation report for TRILL.

The TRILL WG will continue to work with other IETF working groups suchas the ISIS WG, and SDO groups such as IEEE 802.1 through establishedinter-WG relationships and SDO liaison processes, including early andWG last call review by the ISIS WG of documents extending IS-ISrouting.
